Tough workout today. Did a fairly easy warm up of three miles at 8:15/mile and then set-up the Garmin for 1 mile intervals with half mile rests. Plan called for 3x1 mile intervals at 6:26/mile pace. Here are the splits: 6:25, 4:16, 6:23, 4:14, 6:20, 4:13. In all fairness I had a couple of minutes of extra rest before that last interval because I hit the lap button on my gamin by accident and had to do some messing around to get it back to interval mode for the last interval. One thing I noticed is that I do pretty good with each of the intervals until I get to the last quarter mile or so at which point my breathing changes to a much faster rhythm and I really start to struggle. I try to stay relaxed as best I can but the breathing is hard to control. The legs really started to get fatigued by the end of the 2nd interval and I was wishing I only had to do two. The back was no better or worse today but it did seem to feel better, or wasn't as noticable, during the faster miles.
